TO ALL WHOM IT MAY CONCERN:

Beit known that I, WILLIAM F. SHANKS, of Louisville, in the county of Jefferson, and State of Kentucky, have invented a newand improved Mode of Making Brick; and I do hereby declare that the following is n. full and exact description thereof, reference being had to the accompanying drawings.

The nature of the invention consists of a machine, constructed of castings or heavy timbers, or n combination of both. In the accompanyingdrawings#- Figure lis the elevation lof one side, A

Figure 2 the opposite,

Figure 3 a longitudinal section-of the moulds, and

. Figure 4 a plan of the sliding plate.

Tempered clay is put into the hopper U., from whence, through parallel rollers A A, it is passed, properlyV gauged to the thickness of one and width of two bricks, the said rollers moving four inches each revolution of the crank B, caused by the four inches of cogs marked b. The clny is then passed to the belt S, which carries it on the slide G, which, with the belt, nieves in harmony with the rollers A A. The `slide G moves backand forth four inches, by means of the small cogs D -a'nd rod E, stopping directly under the moulds. I f I-he n ioulds,`,.rliicl'lA are a combination of the various parts H H,Q Q, R'R, as shown inplan No. 3, nre worked by av rodpmarked m, attached to the crank B. The tops ofthe moulds R, supported bythe two uprghts P P, attached by'thu'mb-' screws N N to the cross-piece J J, which works on the two uprights K K, are arranged 'to` remain tw'o and a halt' inches above the slide G, until the sides Q Q are brought down the thickness of the brick, when the p iece H, which supports the said sides, comes down on the tops R R, which bringsthe whole moulds down on the slide G, forming the brick. The sides ofthe mould then rise oii' the slide, the -tops remainingpn the bricks until the sides are clear, when the cross-piece H raises the top with it by means of the nuts n n. The slide G then moves back four inches, which leaves the brick on the belt S, and directly'nnder the moulds. The belt vthen l moves with the slide, leaving the brick clear of the moulds, and thc'clay on the slide-G. as before explained.

I claim- 1. The combination of the parts H H, Q Q, R R, uprights P P, thumb-screws N N, cross-pieces J J, uprights K K, and sliding plate G, substantially as described, for the purpose specified. y v

2. In combination with the above, I claim theA rod m, attached to the crank'B, beltS, cogs b, and rodE, substantially as described, for the purpose specified. l l

3. The sliding plate G, operated by means of the cogs D and rod E, substantially as described, for the purpose specified. i I I 4. The rollers A A, adjusted by means of the cogs b and crank-:wheel B, wl1ereby the thickness of the stream or column of mud is regulated, substantially as herein shown and described. i
